The last thing rock star Harper Cushing needs right now is this attraction to her grandmother's helper, Frankie, even if she is sneaky-good on the guitar. Returning to her favorite childhood spot, Gram's nostalgic general store, Harper confronts life-altering decisions: Gram's future welfare, selling the store, and reassessing her own fast-paced "high life." If only she could pull it all off without breaking everyone's heart--including her own.

Having made her own life-altering decision three years ago, Frankie Cosgrove is guardedly single and set to harvest her first cranberry crop. She's devoted to her elderly storekeeper friend, so when the famous Harper arrives, hell-bent on making changes, Frankie's defenses rise.

At least they admit to mutual concerns for Gram and the store, and even each other's heartfelt intentions. But the unexpected musical accord they strike sounds a whole lot like falling in love. Has harmony finally found them?
